immutable-partition

Build Status

A partitioning helper returning an immutablejs Map of Lists:

import partition from 'immutable-partition'
 
const someNumbers = List.of(0, 1, 2, 3)
const evenOrOdd = (number) => number % 2 === 1 ? 'odd' : 'even'
const partitions = partition(evenOrOdd, someNumbers)
console.log(partitions.toString())
// > Map { "even": List [ 0, 2 ], "odd": List [ 1, 3 ] }

Install

npm i -S immutable-partition
 
# or 
 
yarn add immutable-partition

Usage

partition takes the two following arguments and returns a Map<K:string, V:List>.

  • keyForValue(value: any): string must return a string
  • reducible just needs to have a reduce function so it can be any immutablejs structure, a regular array or anything that acts like one.

partition is curried so it can be called in two ways:

partition(keyForValue, reducible)
// or
partition(keyForValue)(reducible)
